Zend Framework, setting up a dynamic menu using a plugin

I wanted to set up the menu in layout.phtml using a dynamic call to the database.
I created a directory in library called plugins.
I put this in application.ini
autoloaderNamespaces[] = “Plugins”
I created a class in the plugins directory called Plugins_Layout with the file name Layout.php

view plaincopy to clipboardprint?

1. class Plugins_Layout extends Zend_Controller_Plugin_Abstract  
2. {  
3.     public function preDispatch(Zend_Controller_Request_Abstract $request)  
4.     {  
5.         $layout = Zend_Layout::getMvcInstance();  
6.         $view = $layout->getView();  
7.         $content_mapper = new Application_Model_ContentMapper();  
8.         $view->menu = $content_mapper->getMenu();  
9.     }  
10. }  

I then added this to Bootstrap.php

view plaincopy to clipboardprint?

1. protected function _initRoutes() {  
2.         ......   
3.        Zend_Controller_Front::getInstance()->registerPlugin(new Plugins_Layout());  
4.     }  

I was then able to create the dynamic menu in layout.phtml

view plaincopy to clipboardprint?

1. <!--?php foreach($this--->menu as $url => $title) { ?>  
2.   
3. a href="/<?php echo $url ?>"><!--?php echo $title; ?--></a>  
4.   
5. <!--? } ?-->  

All was working as I expected.
